Application filed January 17, 1916. Serial Ito. 72,559.

To all whom it may concern:

Be it known that l, Mosnr MoN'rAcnn, a citizen of the United States,residing at Christiansburg, in the county of Montgomcry and State ofVirginia, have invented certain new and useful Improvements inAir-Circulating Apparatus; and I do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilledin the art to which it appertains to make and use thesame.

The present invention relates to improvements in air circulatingapparatuses and more particularly to one designed primarily forventilating purposes, although its application need notbe restricted tothis use.

The objectof the inventionis to improve upon the construction shown in.my pending United States application, Serial No. 60361, filed November8, 1915, the improvements residing in a general'rearrangement of partswhereby the device is greatly simplified.

With the foregoing object in view, the invention consists of certainnovel features of construction and in unique combinations of parts to behereinafter fully described and claimed, the descriptive matterbeingsupplemented by the accompanying drawing which constitutes a part ofthis application and in which:

Figure l is a vertical longitudinal section of the improved apparatus;Fig. 2 is a yertical transverse section thereof taken on the plane ofthe line 2-2 of Fig. 1; Fig. 8 is a detail section. through thepartition and the fans on the opposite sides thereof; and Fig. 4 is adetail side elevation of a portion of said partition and one fan showinga modified form of construction.

ln specifically describing the construction shown in the drawingpreviously described briefly, similar characters will be placed oncorresponding parts throughout the several views and reference will beherein made to the numerous elements by their respective riphery of thepartition 3 is disposed in close proximity to the curved wall 6 of thecasing 1 as clearly shown.

Disposed one on each side of the partition 3 is a pair of rotary fans 7,each of said fans being shown in the present embodiment of the inventionas formed by slitting sheet metal disks radially and by bending theportions thereof between the slits in such a manner as to form angularlydisposed blades 8. The outer ends of these blades are preferably securedby bolts or the like 9 to the partition 3, while the body portions ofthe fans are similarly secured to said partitions as disclosed at 10.

The fans 7 are adapted to draw air into the inlet openings 2 when theshaft is rotated in the direction of the arrow in Fig. 1, and to deliversaid air centrifugally through outlets 11 leading from the casingadjacent the peripheries of said fans. In order that this result may beedectively accomplished, the rear edges of the numerous blades 8preferably contact throughout their length with the partition 3. By thisarrangement,

a plurality of air pockets '12 is provided, said pockets being open attheir front ends to gather air therein, and being open at their outerends to allow this air to be delivered centrifugally through outlets ll.

lln Fig. 4C a partition 3* is shown, and fan blades 8 are riveted to theopposite sides of said partition at their rear edges. This constructionwill be equally as advantageous as that previously described and in somecases may be more desirable.

From the foregoing, taken in connection with the accompanying drawing,the construction and operation of the invention will be readilyunderstood Without requiring a more extended explanation, and obviouslythe apparatus is much simpler and less expensive than that shown in thepending plication above referred to.

claim as my invention:

An air circulator comprising a cylindrical casing having central airinlet openings in its two ends, a one-piece circular part1- tion platedisposed centrally between said.

ends of the casing and having its edge in close proximity to the curvedwall of'said casing, a drive shaft at the axis of the easing on whichsaid partition plate is secured, said shaft extending outwardly throughone of the aforesaid air inlet openings, a plulllll curved wall of saidcasing on each side of the partition plate, said outlets being disposedadjacent the outer delivery ends of the air pockets and being positionedat diametrically opposed points.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses. l
